Netflix patents method to move live data connections between server regions
This filing describes a way to move active, real-time data connections from one server location to another without dropping the user's session. It works by scheduling these connections to close in the old region and immediately reopen in the new one within a set time window.
In the filing’s own words
A computer-implemented method includes listening for an evacuation event indicating that network traffic for a designated geographical region is to be transferred to various other geographical regions. The method also includes identifying open web socket connections assigned to the designated geographical region and determining that the open web socket connections are to be disconnected and transferred to a specific geographical region among the other geographical regions. The method further includes scheduling, in a disconnection schedule, the open web socket connections for disconnection within a specified time interval and, after a specified amount of time designated by the disconnection schedule, closing the open web socket connections in the designated geographical region and reopening the web socket connection in the specified geographical region. Various other methods, systems, and computer-readable media are also disclosed.
